Can ADODC/ADODB be used to connect to SQLite?
If Yes- what is the connection string that can be used?
If No- is it only to connect MS Provided DataBases?
There is a reference that can be used? SYSTEM.DATA.SQLITE (It is not efficient)
Can you suggest me any other references (If not ADO)?
I want to use VB.NET to connect to a SQLite backend.
I Use ADODB Recordset to connect on SQLite database. For that You need this provider and
"DRIVER=SQLite3 ODBC Driver;Database=" & BasePath
for the connection string.
Beware of some restrictions : SQLite has no defined type for each field. Therefore if you misspell a date format or float, the provider with give you an error when you try to update the record.

What is the use of mentioning the database name in connection string while opening a connection from dot net application to SQL server? Because even though we mention a database name in connection string we have to explicitly write the fully qualified name (DBName.schemaName.ProcName) while calling a stored procedure if the default DB is different for that particular user.
Connecting to database from a .NET application is different from accessing a table of different database.
use of mentioning the database name in connection string
so for instance you can use connection string below to connect to myDB at MyServer
Data Source=MyServer;Initial Catalog=myDB;Integrated Security=True
if you will not specify at least these information how your .NET application can connect to a stored procedure (MyProcInMyDB) located in myDB.
Now for part you asked
though we mention a database name while calling a stored procedure if
the default DB is different for that particular user
this is not a normal case to access stored procedure of another database using same connection string if it is a very special case (not likely) then you will do it for calling one or two stored procedures. But if it is required quite often within your application then you should create a separate connection string. Using same connection string and calling like
command.CommandText = "myDB2.dbo.getList"
can result is difficult maintenance and flexibility
I've read about an option in the connection string called MARS (MultipleActiveResultSets), but from what I've gathered it is only a valid argument for Sql Server 2005. Is there an equivalent setting for OleDB to open an access database with multiple readers?
I am aware that I can create multiple connections, one for each reader. I am currently doing this, but it would preferable to execute both readers on a single connection. Here's my current connection string:
"Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:\MyDb.mdb;Jet OLEDB:Database Password=MyPassword"
I am using a vbscript which connects to SQL.
My connection String look like
connectionString = "DRIVER={Microsoft ODBC for Oracle};SERVER=convcsd;User Id=sysman;Password=csaadmin;"
Set connection = CreateObject("ADODB.Connection")
It is working on one server but not on another. it gives an error :
The oracle(tm) and networking components were not found. These
components are supplied by oracle corporation..
You will be unable to use this driver until these components have been
installed.
Please let me know how to add ODBC driver. I researched but not able to get through.
SQL Plus is an Oracle client yes but that is not enough to be able to use your script. You need an ODBC driver and prefable an OleDb driver (is faster) for Oracle on each pc you're going to use your script.
Compare the ODBC drivers between two 2 pc's with the Microsoft ODBC administrator (type ODBC in your startmenu searchwindow) and you will notice the difference. Use your Oracle installpackage and check the option to install the OleDb driver.
There is a Microsoft and an Oracle version, again it is best to use the Oracle driver. The connection string for Oracle OleDb is
Provider=OraOLEDB.Oracle;User ID=<user name>;Password=<password>;Data Source=<data source>
I have a user defined SQL function that I am able to call from management studio using syntax dbo.Function(arg)
Now, when I have to call this function from C# if I don't specify **dbname**.dbo.Function(arg) I get an error that SQL server does not find this user defined function. How can I solve this without specifing dbname ? I already connect to the server using a connection string that specifies the "initial catalog = dbname"
It seems that I cannot reproduce mentioned behavior at this point :-) (either using SQL server 2005 or 2008) I have to put this question on hold
Your connection string needs to specify the database to use initially. It might look something like this:
var cn = new SqlConnection(
"SERVER=SomeServer;DATABASE=SomeDb;Integrated Security=SSPI;"
);
Without that, you're probably being dumped into the master database, which is why you need to fully qualify the function name.
How can I add Microsoft Provider OLE DB for Oracle. I had Microsoft ODBC for Oracle, but I want to add a provider mentioned above.
If I understood your question correctly,
http://www.connectionstrings.com/
will usually help you.
You need (if I remember correctly) OraOLEDB.
Microsoft Provider oledb for Oracle
Means that the connection string will be
Provider=msdaora;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;
Replace Data Source, user name and password as per your configuration.
